The Lowdown
Alright, mate, Rusty here. Let’s have a look at the next couple weeks. We’ve got a solid run of surf on the way, but it’s not all for everyone. The first few days are looking clean and powerful for the experienced crew, then we get a pulse of serious size that’ll have the experts grinning and the rest of us watching from the sand.
The Opening Run: Friday, Aug 14 – Monday, Aug 17
We kick things off Friday afternoon at Lakey Pipe. It’s a reef break that’s known to be consistent, and it’s living up to that. The swell is coming in from the SSW at a solid 5.6ft, with a long 15-second period. That’s proper groundswell, the kind that wraps around the reef and lines up. The wind is a light cross-offshore breeze, so it’s going to be clean. The water’s at a comfortable 80.1°F, which is right around average for this time of year, so nothing weird there. The energy in the water is strong, around 1589, so there’s plenty of push. It’s an intermediate spot, but with this size and power, I’d want your wits about you.
Saturday and Sunday keep the quality high. Saturday morning, the swell bumps up to 6.2ft from the SSW with an even longer 17-second period. The energy jumps right up to 2207, and the wind stays light offshore. By the afternoon, it’s pushing 6.9ft with a 17-second period, and the energy is up over 2600. This is the pick of the first few days. Sunday holds steady with 6.6ft and 6.9ft swells, still from the SSW, with those light cross-offshore winds keeping the surface glassy. Crowds are a real possibility here as it’s a well-known spot, but the waves will be worth it.
Monday sees the swell ease a touch to 5.2ft, but it’s still a clean SSW swell at 14 seconds. The energy drops back to around 1057, still plenty to get you moving. The wind stays in that favorable cross-off direction. It’s a solid, consistent run.
The Mid-Week Push and the Standout: Tuesday, Aug 18 – Wednesday, Aug 19
Tuesday has a bit of a mix. The morning swell is smaller, around 3.9ft from the SW, but the period is a long 16 seconds. The energy is actually quite high at 1953, which tells you there’s some punch in the water. The afternoon sees the size jump back up to 5.6ft, and the energy climbs to 2388. It’s still clean.
But the real standout is Wednesday. This is the one to circle. The swell is up to 8.2ft from the SW with a very long 19-second period in the morning. The energy is massive, hitting 4368. This is serious, powerful groundswell. The winds are light offshore, which is going to make for some proper, grinding barrels on this reef. The period is over 15 seconds, which means it’s very long period, and this spot is a reef, so it’s built for it. This is the day for the experienced surfer. It’s going to be big, clean, and powerful. Crowds are likely because it’s going to be good, but the conditions will be world-class. After this, the water temperature is still in the same ballpark, so no worries there.
The Too-Big Phase: Thursday, Aug 20
Hold on to your boards, because Thursday the swell really jacks up. Both the morning and afternoon sessions are showing a solid 9.8ft from the SW, with a 16-second period. The energy is enormous, over 4300. This is way more than your average surfer wants. It’s going to be

Information about the Lakey Pipe Surf forecast
The above surf forecast table for Lakey Pipe provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Lakey Pipe can be found by selecting the local surf guide option on the grey menu. Our Lakey Pipe surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Lakey Pipe) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Lakey Pipe may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
